SAFETYeRAZOR-BLADE SI-IAItlPENER.

Application filed April 17, 1922. Serial No. 554,044.

This invention relates to an improvement in sharpening devices for safety razor blades, and has for its primary object the purpose of providing improved holding and turning means for the b'lades.

Another object of the invention is in providing an improved arrangement of stropping surfaces which are stationarily held in opposing relation, and between which a razor blade is to be turned in a revolving manner.

A further object of the invention is to provide a closure for a pair of opposing stropping surfaces, and a turning member bearing a razor blade holder which is cooperable with said surfaces, said turning member being provided with improved means whereby a razor blade when borne by the holder can be moved from one stropping surface to the other.

Other and further objects will appear in the specification and be specifically pointed out in the appended claims, reference being had to the accompanying drawings, exemplifying the invention, and inrwhich Figure 1 is a. side elevation of this improved safety razor blade Sharpener Figure 2 is al transverse vertical section taken approximately on the line II-II of F 1.

Figure 3 is a fragmentary horizontal section taken on the line III-III of Fig. 1.

Figure 4 is a fragmentary section similarl -to F 3 but showing the holder and razor blade in a shifted position.

Figure 5 is an invertedy horizontal section taken on the line V-V of Fig. 2.

Refering by numerals to the accompanying drawings 1 designates an inner section of a closure 2 and hinged to said section as designated at 3 is an outer section 4. l

The sections 1 and 4 are preferably circular in formation and shell shaped so as to provide a compartment 5, the inner section 1 being rigidly secured to a vertical wall or member 6 by nailing such as 7, the outer scction 4 being held to the section 1 by the hinge 3 and clasping member 8.

Arranged interiorly of the section 1 is a stropping surface 9 of leather or the like, and arranged int-eriorly of the section 4 is a stropping surface 10, said stropping surfaces being positioned so as to provide a space therebetween.

The section 4 is provided with a centrally arranged opening 11, and arranged around said opening is an inwardly extending flange 12, said opening providing a bearing for a bushing 13.

Turnably mounted within the bushing is the shaft portion 14 of a crank 15, said crank having a leg 16 which is extended within the compartment 5 and between the stropping surfaces 9 and 10, and formed on said crank on the exterior of the section 4 is a handle 17. y

Mounted on one end of the bushing 125 within the compartment 5 is a collar 18, said collar being secured to the bushing by a pin 19, and extending from said collar and arranged parallel to the leg 16 is a resilient membeiyfZO. i

Turnable upon the leg 16 is a blade holder` 21, and formed on one side of said holder is an eye 22 in which the extending end of the resilient member is engaged.

The shoulder 28 of the bushing 13 is provided with avertical groove 24 which adjoins the central opening 25 in which the shaft portion 14 of the crank 15 is mounted, said groove providing means for allowing lateral displacement of the crank within said opening 25, so that the leg portion of the crank can be moved towards or away from eitherl of the stropping surfaces 9 and 10.

In the operation of this improved device, when it is desired to sharpen a razor blade, the clasp 8 of the section 4 is disengaged from the section 1 of the closure 2 and said section 4 is swung on the hinge 3, the crank 15 bearing the blade holder 21 being carried therewith. A safety razor blade 26 is then mounted between the side members 27 of the holder 21 in the manner disclosed in Figs. 1, 3 and 4, and the section 4 is then swung against the section 1 thereby forming the closure 2. The crank 15 is' then pulled outwardly as shown in Fig. 2 therebyT moving the leg 16 thereof adjacent the stropping surfacelO, and owing to the bushing 13 being held against lateral movement by the collar 18 and shoulder 23 thereof, the resilient member 2O borne vby said collar will cause the holder 21 to fulcrum thereon, as the crank 15 is pulled outwardly, thereby swing` ing the cutting` edge 28 to angularly bear against the stropping surface 9, as shown in Figs. 2 and 3.

The handle 17 is then engaged and the crank 15 turned in the direction indicated by the arrow in Fig. 1, the handle during turning being held in its outer moved position, and in which the edge 28 of the blad-e llO 2 lee-aora 26 will be borne against the stropping sui'- face 9 during the t .iiing` movement of the crank.

When it is desir-rd to strop the other side of the edge 28 of the blade 26. the crank 15 is pushed inwardly in which a portion thereof will be fully seated within the groove 211 of the bushing 13, said inward movement of the crank displacing;` the leg portion 16 r thereof adjacent the stroppingv surface 9 and coincident therewith the resilientmember 2O of the collar 18 will cause the blade holder 21 to swing thereon, thereby swinging the opposite side of the cutting' edge of the blade against the stropping surface 10 as shown in Fig. 4.

The groove 24 provides for keying the crank 15 to the bushing 13. in which said bushing will be revolved therewith, and when the crank is laterally displaced in either direction within said bushing, the silient member 2O will control the amount of pressure applied to the razor blade when it is borne against either of the stroppiugsurfaces.

The lateral displacing of the crank .15 towards manipulating,- the blade from oneside to the other of the compartment 5, can be carried on during the turning thereof, and

in which the operation of sharpening a blade is carried on with rapidity.

What I claim is 1. A blade sharpener comprised of a pair of stationarily held spaced apart opposing; stropping surfaces, a blade holder adapted to circular travel between said surfaces, a crank for turning said holder adapted to transverse movement, and means turnable with said crank and co-operable with said holder for moving said holder towards and away from either of said surfaces.

2. A blade sharpener comprised of a pair of stationarily held opposingF flat s roppingr` surfaces, a crank extended from one of said surfaces and turnable therein. anda blade holder secured to said crank between said surfaces, said surface which supports said crank bein g movable from said other surface. 3. A blade sharpener comprised of a pair of opposing` flat strop-ping surfaces, blade holding` means located between said surfaces, means for turning` said holding,- means in a circular direction, said turning' means being,` adapted to transverse movement, and resilient means co-operable with said holder for sustaining an edge of the blade bornethereby against either of said surfaces. r

l-. A blade Sharpener comprisingv a pair of opposing sharpening` surfaces. a bushing transversely supported through one of said surfaces, a crank mounted in said bushing and turnable therewith and adapted to transverse movement therein. a blade holder mounted on one of the legs of said crank between said surfaces, and means extending from said bushing` to said holder for movine; said holder towards and` away from either of said surfaces.

5. A blade Sharpener comprising avpair of opposing sharpening surfaces, a bushing transversely supported through one of said surfaces, a crank mounted in said bushing' and turnable therewith and adapt-ed to transverse movement therein, a blade holder swingably mounted on one of the legs of said crank between said surfaces, and pivoting; means extending from said bushing to said holder for moving said holder towards and away from either of said surfaces.

6. A blade Sharpener comprising` a pair of opposing sharp-ening?,` surfaces a bushing' transversely supported through one of said surfaces, a crank mounted in said bushing' and adapted to transverse movement therein, means for keyingsaid bushing and said crank together, a blade holder mounted on one of the legs of said crank between said surfaces, and means extending from said bushing to said holder for moving` said hold` er towards and laway from either of said surfaces.
